LOCK FOR'AXLE-SKEIN NUTS.

SPECIFICATION forming part of Letters Patent No. 624,619, dated May 9, 1899.

Application filed June 2, 1898. Serial No. 6821391. (No model.)

T0 all whom, it may concern:

Be it known that we7 AUGUST BROCK- soHMIDT and CLEMENT L. STUCKEY, citizens of the United States, residing at Pierce City, in the county of Lawrence and State of Missouri, have invented a new and useful Lock for Axle-Skein Nuts, of which the following is a specification. Y

, Our invention is in the nature of a lock for 'axle-skein nuts, the object of the invention being to provide a simple, cheap, and easilyapplicable device whereby the nuts 4which hold a wagon-wheel in place will be prevented from being lost offrespecially when backing the wagon, thereby obviating the trouble, annoyance, and positive danger to life and property caused by such accidents.

With this object in view the invention consists in a clip made of sheet metal having a rectangular central opening in its center to fit over a square end of an axle and having upper and lower horizontal iianges to em` brace the top and bottom of the nut, the upper flange being bent downward at its inner edge to engage in a groove in the top of the e nut and the lower flange being provided with a plate-spring secured to its inner side to engage in a like groove in the bottom of the nut.

Our invention further consists in the improved construction, arrangement, and combination of parts 4hereinafter fully described c and afterward particularly pointed out in the claims.

In order to enable others skilled in the art to which our invention most nearly appertains to make and use the same,we will now proceed to describe its construction and operation,ha'v ing reference to the accompanying drawings, forming part hereof, in which- Figure lis a perspective view of the hub and part of the spokes of a wheel mounted on an axle having the skein-nut secured in place by means of our invention. Fig. 2 is a view illustrating the axle and skein in elevation and the nut and lock in section. Fig. 3 is a view of the same parts all in elevation. Fig. 4 is a detail perspective view of the nut, and Fig. 5 is a detail perspective view of the lock.

Like letters of reference indicate the same parts in all the figures of the drawings.

Referringto the drawings by letters,v A indicates a wheel-hub, and B the spokes, the wheel being of such construction as is usually used on an axle C with skein D.

E indicates the nut to hold the skein on the axle, the axle being provided with a square reduced end G. e

l-I indicates our improved locking attachment, being a metal clip comprising a lnain body I, with central rectangular opening J to engage over. the square end G of the axle and flanges K and L to embrace the top and bottom of the nut, an inwardly-turned flange K on the flange K to engage in the groove in the top side of the nut, and a plate-spring L,

secured to the inside of the flange L, to engage ing the spring until the flange K is clear of its groove, and then draw the flanges K K' oft the nut, when the whole device may be removed. The opening J is of the same width as the reduced square end G of the axle, but is lof a length .sufciently greater to permit of the movement up and down of the lock required in affixing and removing it. It may be formed by cutting or punching all the material out of the sheet or' by turning part of it out, as at J', to form flanges to bear against the sides of the reduced end G of the axle.

The terms top and bottom flanges and top and bottom sides of the nut are used herein only withV reference to these parts in the positions illustrated in the drawings, the flanges being adapted to the grooved sides of the nut no matter in what position the nut is placed.

The construction, operation, and advantages of our-invention will be readily understood from the foregoing, and while we have illustrated and described the best means now known to us for carrying out our invention we do not wish to be understood as restrict- IOO ing oursel ves to the exact forms and constructions shown, but hold that any slight changes or variations therefrom, such as might suggest themselves to an ordinary mechanic after having seen our inventiomwill clearly be oomprehended Within the limit and scope of our invention.

Having thus fully described our invention, what We claim as new, and Wish to secure by Letters Patent of the United States, is-

1. A locking device for nuts of axle-skeins, comprising a metallic plate or sheet having a rectangular opening to engage the reduced square end of an axle, top and bottom flanges to engage over the top and bottom sides ofthe nut, a vertical inwardly-turned flange at; the

. inner end of the top liange to engage in a groove in the top of the nut, and a plate-sprin g secured to the inside of the bottom flange to engage in a groove in the bottom side of the nut, substantially as described.

2. The combination with an axle having a threaded portion and a reduced square end, of a nut threaded on the axle having grooves in its top and bottom sides, and a locking at- 4opposite edges, of a locking-plate having a bolt-opening formed With flanges adapted to engage upon opposite sides of the bolt, and formed on opposite edges with flanges, one ofv said flanges having an inWardlyturned edge adapted to engage the groove formedV in the opposite edge ofthe nut, substantially as described.
